Input/Output Impedance (Unit: Ω)

Signifies the internal impedance value of the input and output side at the center frequency of

ceramic piezoelectricity, and it is expressed in Ω. It causes no problem even if the input and the

output are used in reverse with ceramic piezoelectricity, since the input and the output impedance

are in a symmetry of substantially almost same value.

Impedance Matching

When connecting one electric circuit to another, or a component to another, or one electric circuit to

a component, the electric energy is supplied most efficiently from the signal source to the load if the

signal source impedance and the load impedance are same.

If these impedances are mismatched, electric energy escapes in form of a reflection. To match the

signal source impedance and the load impedance is called the impedance matching. This is very

important for ceramic piezoelectricity, as an improper impedance matching may cause various

troubles.
